PURPOSE: A column for carrying out an isotope exchange between a liquid substance and a gaseous substance is provided. CONSTITUTION: In a column for carrying out an isotope exchange between a liquid substance(L) and a gaseous substance(G) using a catalytic reaction in which the isotope exchange between molecules of the vaporized liquid substance(V) and molecules of the gaseous substance(G) takes place through a heterogeneous catalysis, the column comprises a plurality of modules(M) which are arranged vertically one above the other and which are in each case subdivided into two regions K and A which are serially connected by a connection region(C), with it being possible to carry out the catalytic reaction in the region K on a first packing(2), with it being possible to carry out a substance exchange between a liquid and a gaseous phase which contains vapor in the region A by means of a second packing(3) for compensating substance concentrations, with a transport of the gaseous substance(G, V) which contains vapor being driven through the modules as a result of pressure gradients during the operation of the column; with the transport direction being changed at least once in the connection region, and indeed from a downward direction to an upward direction, whereas the liquid substance(L) is forwarded downwardly through the modules through the action of gravity alone, wherein the transport through the modules(M) of the gaseous substance(G, V) which contains vapor in each case is conducted upwardly through the region K, downwardly through the connection region(C) and upwardly through the region A.
